Fig. 5From: Integrated heterodyne laser Doppler vibrometer based on stress-optic frequency shift in silicon nitrideSimulated suppression ratio of the sidebands at the output of the SSB-OFS with relation to the deviation of a the phase modulation, b the power splitting ratio and c the phase difference of the optical circuit. The suppression ratio of the sidebands is measured in the electrical domain (SBSR) after coherent photodetection. Phase modulation of 0.2 π peak-to-peak is assumedBack to article page
